ATTACHMENT FOR STEAM-ROLLERS.

Specification of Letters Patent.

' Patented Nov. 10, 1908.

Application filed January 31, 1908. Serial No. 413,677.

To all whom it may concern:

Be it known that I, GEORGE J. NEYERLIN, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Attachments forSteam-Rollers, of which the following is a specification.

This invention relates to steam rollers and more particularly toattachments whereby oil may be automatically supplied to the boiler andwith hot water from the latter sprinkled upon the front roller, saidattachments also embodying means for sprinkling the rear roller.

A further object is to produce attachments of the character specifiedwhich are inexpensive and which can be easily, quickly and cheaplyapplied to a steam roller.

With these and other objects in view the invention consists in certainnovel and peculiar features of construction and organization ashereinafter described and claimed; and in order that it may be fullyunderstood reference is to be had to the accompanying drawing, in which,

Figure 1, is a side elevation of a steam roller equipped withattachments embodying my invention, a part of the rear end of the rollerframe being in section. Fig. 2, is a section on the line 11-11 of Fig.1, with the front roller and other parts forward of the boiler, omitted.Fig. 3, is .a detail perspective view of a spray pipe forming part ofthe attachment.

In the said drawing, 1 indicates the rear and 2 the front roller of astreet rolling machine, the shaft 3, of the front roller being journaledin bearings 4 mounted on the frame 5. The rear end of the frame is bentupward and rearward to approximately gooseneck form at 6 as customaryand swiveled in the rear end of said frame is the usual yoke 8 forming ajournal for the shaft 9 of roller 1.

10 is the boiler mounted on the base plate 11 secured to the frame inany suitable manner. 12 is the tool box and 13 the water tank alsosupported in the usual manner.

14 is a pipe communicating at one end with tank 13 in the usual manner(not shown) and connected by valve-controlled pipe 15 with a valvecontrolled pipe 16 connected by pipe 17 with the central gage cock 18 ofthe boiler, the latter being also equipped as usual with gage cocks 19and 20 respectively above and below gage cook 18 and with a water glass21, the gage cocks being usually manipulated by the engineer for thepurpose of determining the height of water in the boiler when it is toodark or inconvenient to ascertain such height from the water glass. Pipe17 is also equipped with a valve-controlled blow off cook 23. Coupled topipes 15 and 16 in front of their respective valves is a pipe 23,connected by a flexible pipe or hose 24 to a short pipe 25 connected bya T-coupling 26 to the horizontal jet pipes 27 secured to the undersideof the tool box above the roller 2 for a purpose which hereinafterappears.

28 is a pipe communicating with the boiler in about the plane of thelower gage cock and with the stand pipe 29 equipped with a steam gage 30at its upper end. Communicating with said pipes 28 and 29 is adownwardly extending valve controlled pipe 31 coupled to a rearwardlyextending pipe 32 underlying platform 33 and connected by a flexiblepipe or hose 34 to the transverse jet pipes 35 of the same constructionas the jet pipes 27 but supported above the rear roller 1 by'brackets36, one only appearing) secured to .the yoke 8.

37 is a valve-controlled pipe communicating with the boiler above thewater line and equipped at its lower end with an injector 38 connectedby a pipe 39 with the lower end of the boiler and communicating with theinjector is a pipe 40 connected by a horizontal pipe 41 with the rearend of pipe 14, a valve 42 controlling communication between pipes 14and 41. 43 is an oil tank having a depending valve controlled pipe 44communicating at itslower end with pipe 41 between the valve 42 and pipe40. The machine is operated and controlled in the usual manner and if itis desired to simply wet the roller 2 for any reason, the engineer opensgage cook 18 and the valved pipes 15 and 16, this action resulting underthe pressure of steam in the boiler, in the discharge through pipes 15and 16 of hot water with suflicient force to create an upward suctionthrough pipe 15 for the purpose of drawing cold water from tank 13through pipe 14 and said pipe 15 and discharging it through pipe 23 hose24 and the jet pipe 27 onto roller 2, this discharge incidentallyskimming the foam and surface mud. from' the water.

I have found in practice that in the cold seasons of the year asphalttends to stick to the roller, particularly the front roller and thatthis difliculty may be avoided by Warming said roller. To accomplishthis purpose the valve of pipe 15 is left closed and gage cock 18 isopened, the result being the sprinkling of hot water by jet pipe 27 ontoroller 2. The valve of pipe 16 is normally open and is only closed whenit is not desired to heat the roller. When thus closed the gage cock isopened occasionally to try the water and blow the foam and surface mudtherefrom to keep the lines and flue sheet clean.

If it is desired to also heat roller 1, the valve of pipe 31 is alsoopened to permit water to be forced from the boiler through pipe 28,pipe 31 and hose 34 to jet pipe 35, by which it is sprinkled on roller1, it being understood in this connection that because of the violentagitation of the water in the boiler most of the impurities whichcollect on the surface are discharged therefrom with the water onto therollers and thus tend to keep the boiler clean and free of scale-formingproperties.

I have also found in practice that by impregnating thewater of theboiler with oil or an oily mixture commonly known as boiler compound, bywhich the life of the boiler is lengthened, and discharging suchoilimpregnated water on the rollers and particularly roller 2, that thetendency of the asphalt to stick is even less marked than where hotwater alone is used. Furthermore that such mixture tends to close thepores of the asphalt upon which the roller is operating and thusincreases its durability. This oil may be introduced into the boiler inany desired manner and as a rule a cupful is suflicient to accommodate adays operation of the machine for the reason that the agitation of theboiling water is so violent that it keeps the oil in circulation andthus prevents but a small quantity of the same being discharged witheach discharge of hot water. If'desired, however, oil can be kept intank 43 and when it is desired to supply the boiler with a quantity ofoil the valve 42 and the valves of pipes 37 and 44 are opened to permitsteam to be discharged downward through the injector and create asuction which draws water from pipe 14 and oil from tank 43 into theinjector from which it passes downward through pipe 39 into the boiler,said valves being reclosed when the boiler is charged with suflicientoil. WVhen water alone is to be discharged into the boiler the valve ofpipe 44 is of course closed.

When the machine is to remain inoperative for any period-all night forinstance 44 for an instant, and then reopens such valve and anothersmall quantity of oil will be carried into the boiler and another breakwill follow. He then recloses the valve of pipe 44 and then reopens thesame, continuing this operation until all of the compound,

if desired, is withdrawn from the'tank and discharged into the boiler,where it stands overnight and prevents the formation of scale to anyconsiderable degree. Another feature of advantage derived by the use ofoil in the boiler, is that it has a tendency to lubricate the valves andoints of the various pipes through which it passes and increases theirperiod of service. The compound softens and loosens the scale formedduring the day and such matter is blown off in the morning through thejet pipes before the engine is started, so that the steam afterwardadmitted to the cylinder (not shown) shall be free from impuritiesinjurious to the valves of the cylinder. steam through the presence ofoil in the boiler, tends to lubricate the valves of the cylinder.

From the above description it will be apparent that I have produced anattachment for steam rollers possessing the features of advantageenumerated as desirable and I wish it to be understood that I reservethe right to make such changes in the form, proportion, I detailconstruction and arrangement of the parts as shall not be a departurefrom the spirit and scope of the appended claims. 7

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, is:
